Common Maintenance Methods Routine maintenance involves the following methods:

Observation

Unplugging/plugging

Replacement

Self-loop

Step-by-step

Self-check

Cross-connection

Pressing

Alarm log analysis

Subscriber line test

Online test

“Ping”

Observe the status of indicator lights on the panel, such as the RUN and ALM lights.

Observe the status of alarm indicators on the alarm box.

Observe alarm messages on the NMS (maintenance console).

NOTE: Correct judgment based on observation is the key for fault analysis and handling.

For a circuit board fault, plug/unplug the circuit board and external connectors to clear the poor contact fault or processor abnormity.

NOTE: Make sure whether the board is hot-swappable. Remember to wear anti-static wrist strap.

Replace the suspected board with a normal one to judge whether the board is faulty or not. If the plugging/unplugging method does not work, this method can be used. For the precautions in plugging/unplugging or replacing a board, see Appendix A Board Replacement.

When the system is partially faulty, isolate the faulty part from the related circuit boards or shelves to judge whether the fault is due to mutual influence. For the board with both input and output interface, take the self-loop test on the input/output interface to isolate and remove the related problems.

Pull out all cards except the power board. Firstly, insert the control board. After the control board works normally, insert the subscriber cards in sequence. If the fault occurs again when one card is inserted, it is sure that this card or the card slot causes the fault. Modify this card or backplane.

When the system or the circuit board is powered on again, the system can verify the fault through self-test. In the power-on self-test of a common board, the panel indicators flash regularly, which tells whether it has problem or not.

Unplugging /Plugging

Replacement

Self-loop

Step-by-step

Self-check

Chapter 2 Overview


If it is failed to locate a sub-node fault, cross connect lines with signals of the same nature to determine the faulty point and faulty type. For instance, to judge whether 2M cable is faulty or not, use the normal 2M cable to have a check.

Press chips, cable connectors, etc. to remove faults resulting from poor contacts.

View the current alarm and history alarm messages shown on the NMS terminal. Judge whether the system runs normally and to locate faults. The current alarm message disappears after a fault is removed.

Measure the parameters of subscriber internal line, external line and terminal through the subscriber line test system, to judge subscriber status.

Perform online test to trace the service flow, for judging and locating the faults.

For the narrowband service, use a line tester and a signaling analyzer to test the line status and signaling interaction flow.

For the broadband service, use a line tester to test the ADSL port and line.

To locate the faults of the service network and the NMS network, ping the IP addresses of the nodes.

Precautions in Routine Maintenance Mind some precautions in routine maintenance:

Keep the equipment room in normal temperature and humidity. Keep the environment clean and clear. Protect the equipment from dust and dampness. Prevent rodents from entering the equipment room.

Ensure stability and reliability of the primary power supply of the system. Check the grounding and lightning protection ground of the system periodically. In particular, check the lightning protection system before and after storm. Make sure it is in good condition.

Establish a complete set of maintenance regulations for the equipment room and standardize the routine maintenance work. An exhaustive duty log is available to provide details about system operation, version, data change, upgrading and troubleshooting on day-to-day basis for follow-up analysis and troubleshooting in the event of a fault. Prepare a work-shift record to specify the responsibility clearly.

Never play games on the PC terminals. Do not install, run or load any other software unrelated to the system on the terminals. Do not use the PC terminals for other purposes.

Cross-connection

Pressing

Alarm log analysis

Subscriber line test

Online test

“Ping”



Set different NMS passwords for different access rights. Put them under rigid management and make changes to them periodically. In addition, keep the NMS passwords only accessible to maintenance personnel.

To help the maintenance personnel get certain knowledge about the equipment and network, arrange trainings for them before they take the post. During maintenance operations, they need follow the instructions described in the relevant ZXMSG 5200 manuals. To avoid any accident, they need wear antistatic wrist straps before touching the equipment hardware. The maintenance personnel must have good work attitude and skills, and would like to keep on learning to improve their own skills.

Do not reset the equipment, load or change data casually, especially, the data of the NMS database. Back up the data before any change. Do not delete the backup data until the equipment runs properly for some time (usually a week) after any data modification. Take the record after any data change in time.

Prepare commonly used tools and meters. Check meters regularly to ensure they work properly. Commonly used tools and meters are as follows:

Straight screwdrivers and cross screwdrivers

Signaling tester

Diagonal pliers

Network cable pliers

Mmultimeter

AC power supply for maintenance purpose

Extended power caber and sockets

Telephone line

Ethernet cable

Check the spare parts regularly. Ensure that they are in a sufficient inventory and good condition. Keep them away from moisture and mould. Keep the spare parts separately away from those damaged parts. Label the spare parts for distinction. Enough commonly used spare parts must be available.

Put the software packages and documents which might be used duringmaintenance in a easily accessible place.

Make sure that the illumination in the equipment room meets the maintenance requirements. Fix the damaged light as soon as possible.

Handle the fault promptly. If the maintenance personnel are failed to solve the problem, contact the local office of ZTE Corporation immediately.

Chapter 2 Overview


Ensure all maintenance personnel know the contact information of the local ZTE office. Thus, they can contact ZTE for support in time. Remember to update the contact method.

Three kinds of lighting facilities (for common use, for assurance and for emergency) are in good condition. Fire control equipment is available. The floor is paved as required without any damage. The supports are well grounded.

The holes between rooms and the outlets, and the gaps along the cable channel are well seamed. The sealing material is free of deformation or break. The cable trough is moisture-proof and the cable protection layer is free of mildew.

Once the equipment room doesn’t meet the specified requirement, contact the relevant department.

Disassemble the dust-proof nets at the bottom and side of the cabinet. Wash them with neutral detergent. Dry them thoroughly. Check whether any foreign matter remains in the cabinet. If any, remove it. For any problem which is difficult to handle, report the relevant department in time.

Monthly Maintenance Item 2 (Checking the Power Cables and Ground Wires)

Check whether the power cable and ground wires are connected properly and free of rust.

Both power cables and ground wires are in proper connection and free of rust. Note: Because the ZXMSG 5200 (V2.0.2) cabinet is directly connected to the external line, it is forbidden to combine the distribution frame ground (lightning protection ground) with the working ground and the protection ground, avoiding equipment damage due to the invasion of abnormal voltage and current. In addition, remember to equip the related lightning protection device before connecting the 220V mains supply directly to the primary power supply.

If there is anything wrong with a power cable or ground cable, reconnect or replace it.

All subscribers on the whole shelf still work normally.

If changeover fails, replace the ICS board. If the fault is still there, contact the technical personnel in time for troubleshooting.

Note: Carry out this operation at night when there is little traffic. Report the superior authority in advance.

Quarterly Maintenance Item 2 (Maintaining Storage Battery)

Normally, the storage battery is in the status of float charging. Be sure to regularly check the float charge voltage and maintain it within a specified range. The storage battery needs an equalized charge quarterly.

Disable the AC input and supply power with the storage battery. Execute the MML command to collect real-time power parameters. When the voltage of the storage battery drops to -46 V, restore the AC input. Use the MML command to set the charging mode as equalized charge. When the battery is fully charged, set the charging mode as float charge with the MML command.

Keep the temperature in the battery room under 30 °C. Keep the storage battery clean, dry and away from the fire source.

Note: Read the storage battery guide carefully before using any kind of storage battery since there are a variety of storage batteries.

Quarterly Maintenance Item 3 (Testing the Ground Resistance)

Board Replacement

Appendix A covers the following topics:

Replacement of ICS

Replacement of POWER Boards

Replacement of Other Boards

Overview Replacement of faulty boards is a commonly used and very important maintenance method during daily maintenance. We recommend that the equipment maintenance personnel, before replacing a board, should contact the related technical personnel or ZTE’s local service engineers for technical support and guidance.

Replacement of ICS The ICS cards are hot-swappable. It means that it is possible to replace the ICS card with the power on. It is not required to turn off the power supply of the sub-shelf. The ICS card works in the active/standby status. When an ICS becomes faulty, there is not any influence on the service of the unit. The maintenance personnel can replace the faulty ICS card at any time.

Based on fault observation and analysis, verify that the card is faulty and needs to be replaced. Verify that the spare part is well functioning, and the model and program of the spare card are identical to those of the faulty card. Prepare an anti-static bag, an anti-moisture bag, a classified cartoon, and some adhesive labels for labeling.

Follow the steps below to replace the ICS card.

1. Wear an anti-static wrist strap.

Introduction

Preparation

Procedure



2. Pull the extractor of the fault card outward and downward with one hand using moderate force. When the card detaches with the slot and ejects, hold the lower edge of the card with the other hand, and gently pull the card out. During this process, avoid touching components or circuits on the card with the hand.

3. Put the removed faulty card into an anti-static bad lined with an anti-moisture bag, and label the bag to indicate the card model, program version and the word “Faulty”. Place the fault card into a cartoon as per the classification. Label the cartoon as well at the outside to facilitate consequent identification and proposal.

4. Verify the name of the spare card and insert it into the corresponding slot in the shelf by pressing the extractor on the card with a thumb and pushing the card in with moderate force until the extractor is caught, which means that the card is in position.

After the card is inserted, there will be a self-test process which may take some time. If the self-test succeeds, the indicators will start normal indication and the service will resume, indicating that the replacement has succeeded. If the card self-test fails, namely if the self-test does not stop, the final indication is abnormal, and the service of the related unit does not resume, the replacement has failed. Check whether the spare board is damaged or whether the fault is on another board.

NOTE: Copy the above data to the ICS card.

Replacement of POWER Boards For the ZXMSG 5200 (V2.0.2) system, the power boards of POWER H, POWER K and POWER G are available. For the three types of power boards, the replacement procedures and precautions are the same. Here, take POWER H board as an example.

The POWER H board does not support hot swapping; namely, it is strictly forbidden to replace the POWER H board. Be sure to turn off the power switch before replacing the board.

Based on fault observation and analysis, verify that the board is faulty and needs to be replaced. Verify that the spare board is well functioning, and the model and program of the spare board are identical to those of the faulty board. Prepare an anti-static bag, an anti-moisture bag, a classified cartoon, and some adhesive labels for labeling.

Follow the steps below to replace the Power H board.

2. Turn off the switch of the faulty POWER H.

3. Pull the extractor of the fault board outward and downward with one hand using moderate force. When the board detaches with the slot and ejects, hold the lower edge of the board with the other hand, and gently pull the board out. During this process, avoid touching components or circuits on the board with the hand.

4. Put the removed faulty card into an anti-static bad lined with an anti-moisture bag, and label the bag to indicate the card model, program version and the word “Faulty”. Place the fault card into a cartoon as per the classification. The cartoon should also be labeled at the outside to facilitate consequent identification and proposal.

5. Verify the name of the spare board and insert it into the corresponding slot in the shelf by pressing the extractor on the board with a thumb and pushing the board in with moderate force until the extractor is caught, which means that the board is in position.

6. After inserting the POWER H, turn on its power switch.

Check whether the indicators are in normal statuses and whether the service has resumed. To minimize influence on services, the board should be replace in the time section with the lowest traffic load in the night when.

If the final indicators are in abnormal statuses after the replacement, the replacement has failed. Check whether the spare board is in good condition.

Replacement of Other Boards For the ZXMSG 5200 (V2.0.2) system, the other boards refer to the service boards and subscriber cards, such as the TPU, ODT, ALC, DLCC, AUDB and DIB boards.

All the other boards are hot-swappable. It means that it is possible to replace the card with the power on. It is not required to turn off the power supply of the sub-shelf.

Based on fault observation and analysis, verify that the board is faulty and needs to be replaced. Verify that the spare board is well functioning, and the model and program of the spare board are identical to those of the faulty board. Prepare an anti-static bag, an anti-moisture bag, a classified cartoon, and some adhesive labels for labeling.

Follow the steps below to replace the board.
